CHURN.

The present invention relates generally to churns and the like and more particularly to an operating mechanism therefor. The principal object of the invention is to provide an operating mechanism of this nature which will `be of an extremely simple, durable, and inexpensive struct-ure, one which isefiicient and reliable in operation, and'vvell adapted to the purpose for which itis designed. A particular object of the inventionis to provide an :operating mechanism of this nature which will be sanitary and which in operating the churn will not allow any oil or grease to come intro contact with the churn thus eliminating the danger of such oil or `grease being mixed with the contents of the churn. y

Another 'particular object of the invention is to provide a Vdevice of this nature which iscapable of operating in asimple and Vquiet manner providing for the long and useful life of the several parts of which the mechanism is composed. i 1

A sti-ll furtherobject of the invention is vvto providea device `of this nature which is useful in operating various different attachn'ient's y flVith the above and numerous other objects in view als will. appear 'as the description progresses, Ath'ejinvention resides in certain novel features of construction, and -in the combination and arrangementof parts vas wili be hereinafter more fully described and claimed.

Figure 5 is a lsection on line. 5-5 of Figure 2. 1

y Referring to the. drawing in detail it will be seen that C designates the cabinet Igenerally which includes vthe lower portion A and the upper portion B. The upper portion l contains 'the churn While theflower` portion A contains the operating mechanism therefor. c i

The lower compartment A is provided in its rear Wall with a door 8 hinged as at 9 and normally7 held closed by latch mechanism 10. It isv to be noted that the door 8 swings vertically the hinges being located at the lbottom thereof. The door-8 functions as -a platform and is provided in itsy side edges The upper face or innerl face of the vdoor platform. 8 is provided. with a .plurality of notched cleats 14 which are arranged vin af circle for receiving screws or other projections -15 yon thel bottom portion of anice- .cream freezer' 16 supported on the door platform :when in its open position. ,This

ice cream freezer is further supported and braced by a pivoted arm 16 hinged at 17 within the lower compartment `and having a hooked end receivable ina keeper' 18 mounted onthe freezer 16. The freezer is constructed with an enlargedsprocket wheel 19 which is also provided with a handle-.2O .in order that the same may be manually operated if necessary. A sprocket chain 21 is provided for theoperation of this sprocket 19 and when not in use is adapted tovbe yhung on a pair of vhooks 23 depending from the upper wall of the lower compartment as is disclosed to advantages in Figures 1 and 2. An electric motor 25 isV mounted within the compartment A adjacent the front end' thereof and is energized through a; suitable *cable "The pulley 27 lof this motor has trained thereover a belt 28. A shaft 29 is journaled invthe standards 30 rising from base 31 which is mounted on the bottom of compartment A. A pulley 32vis keyed to this shaft and has trained thereover the belt 28 so that upon opera-tion of the motor 25 the shaft 29 is rotated. Apulley 34 is valso keyedto lan intermediate portion ofthe shaft 29 and is of a smaller diameter thanpulley 32- A vbase 35 is also mounted in the compartment A on the bottom thereof a distance from base 31 and extending parallel there- -ate the ice cream freezer scribed. A pulley 44 is fixed to the shaft with and under the upper compartment B. Standards 36 rise from the end of this base and have journaled therein a s-haft 37 which is driven through a pulley 38 mounted thereon over which a belt 39 is trained, this belt also being trained over pulley 34 on shaft 29. It Will thus be seen that upon operation of the motor 25 that th'e shaft 37 will be `rotated through the intermediacy of pulley 27, belt 2S, pulley 32, shaft 29, pulley 34, belt 39, and pulley 38. The journals of shafts 29 and 27 are lubricated by means of oil cups 40. The pulleys 32, 34 and 38 are keyed or iixed to their respective shafts by means of set screws 42 passing through the collars thereof and engaging the shafts.

A sprocket 43 is mounted to the shaft 37 by means of one of the screws 42 and it is over this sprocket that the chain 21 is adapted to be trained when it is desired to operheretofore de- 37 by one of the screws 42 and is adapted to have a belt 45 trained thereover which is `manually rotated for rotation of shaft 37 through the intermediacy of pulley 44 and 46 over which is trained the belt 45.

A crank 5l is mounted at each end of the shaftv37. These cranks areengaged with pitmen 52 which extend upwardly through slots 53 provided in the top of compartment A up into compartment B. A churn 54 is positioned Within the compartment B and may be of any preferred construction in the present instance consisting of the usual container having the agitator 55 located therein and adapted to be reciprocated by a rod 56 which is slidable through a suitable closure A pair of inverted L-shaped standards 59 extend upwardly from the bottom of the compartment B and the upper or shorter arms 60 thereof support slide bars Gl which are of L-sliaped structure the longer arms providing the slides Whereas the lower and shorter arms 62 are engaged with intermediate portions of the longer arms of standards 59. The standards 59 are braced bvbars 63 Which are attached to the bottom of compartment B in any suitable manner and their upper ends are fixed to the upper ends of the standards by means of bolts 64 or in any other suitable manner. The standards 59 are also braced in res ect to each 'other by cross rods 65. A hea 66 is provided adjacent its .ends with sliding journals G7 for receiving the slide barsl and trunnions 68 project beyond these slide bars into journals 67 positioned in the upper ends of the pitmen 52. The intermediate portion of this head ('56 is fixed to the upper end of the rod 5G which is attached to the agitator 55.

From consideration'of the device as'thus far described it will be seen that upon rotation of the shaft 37 either by means of the motor or the manually operating mechanism that the cranks 5l will be rotated so as to reciprocate the pitmen 52 thus moving the head 6G up and down on theslide bar (il. This will cause the reciprocat-ion of rod 56 and agitator 55 thus efliciently operating the churn. In this connection particular attention is called to the fact that all parts which require lubrication are .so situated that the-lubricant cannot possibly drift downwardly on the churn. The slide bars 61 are located, as is shown to advantage in Figure 2, to each side of the churn as are also the pitmen and the trunnions of the head The churning operation, therefore, is absolutely sanitary as far as lubrication is concerned.

The .shaft 29 is extended through one side Wall of the lower compartment as will be seen by referring particularly to Figure 4, the extended portion of the shaft being designated specifically by the numeral 70. This extension 70 has mounted thereon a pulley 7l located in a. guard housing 72 on the outside of the lower compartment. A belt (not shown) may be trained over pulley 71 for the opera-tion of various attachments.

In Figure 3 I have shown that the upper compartment B is provided in its front Wall With a door 78 hinged at 7 8 and having its upper portion provided With a transparent panel 79 in order that the operation of the churn may be partially seen Without opening the door. `By opening this door the churn may be easily placed in and out of compartment B and ready access be had to the operating parts Within the compartment for lubricating and repair purposes.

It is preferable to mount the cabinet C on castors 80a or the like in order that it may be conveniently moved from place to place. It is my desire that the cabinet should have an attractive design as is shown to advantage in Figures 1 and 2. The device is possessed of a simple, strong, and durable structure. The parts are of such a nature that they cannot very easily become out of order and Will operate in a noiseless and smooth manner. It is thought that the structure, operation and advantages of the invention should be now clearly understood without more detailed description thereof.

lVhile the preferred embodiment of my invention has been described in detail with a certain degree of particularity, it will be understood that I do not Wish to be limited to the particular construction setforth, since various changes in the form, material, proportions, and arrangement of parts, and in the details of construction may be resorted to Without departing from the spirit and scope of the invention as hereinafter claimed or sacrificing any of its advantages.

I desire to call attention to Figure Which illustrates the ratchet Wheel 80 of pulley 44 which is separate from its collar 81. A pivoted dog 83 on pulley 44 is engageable With the ratchet Wheel so that the pulley 44 is free to remain stationary when the shaft 37 is operated by the motor, but made to rotate shaft 37 when operated'by crank 50.

Having thus described my invention what I claim as new is:

l. In a device of the class described, a cabinet, a platform door hinged at its bottom to the bottom of the cabinet,'said door provided in its side edges with notches, legs pivotally mounted in said notches, means for supporting and holding an agitator device on the platform door, a shaft rotatably mounted in the cabinet, meansin the cabinet for operating the shaft, and a chain operable by the shaft for operating the agitator device.

2. In a device of the class described, a cabinet, a platform door hinged at its bottom to the bottom of the cabinet, means for supporting and holding an agitator device onv the platform door when opened, a shaft rotata ly'mounted in the cabinet, means in thel cabinet for operating the shaft, and a chain operable by the shaft for operating the agitator device.

3. In a device of the class described, a cabinet, a platform door hinged at its lower end to the bottom of the cabinet, means for supporting said door in an open lowered position, means for holding an agitator' device on said door when open, operating means in the cabinet, andmeans to operatively connect said operating means to said agitator device.

In testimony whereof I afiix my signature.
